3 Claims.

commercial type of wringer in which my invention hasbeen embodied;

Fig. 2 a fragmentary vertical section axially through the rolls;

Fig. 3 a fragmentary elevation of a portion of the pressure-controllingmeans;

Fig. 4 a vertical section of the parts shown in Fig. 3;

Fig. 5 a considerably magnified fragmentary sectional detail of theparts shown in Figs. 3 and 4;

Fig. 6a fragmentary horizontal section of the water deflector andassociated parts; and

Fig. '7 a perspective of the water deflector.

In the drawing indicates the base of the wringer formed mostconveniently of pressed sheet metal and comprising channel-shaped endstandards I I, ll comprising vertical inner flanges l2, l2, intermediateflanges I3 and end wall I4, the flanges l2 and I3 being spaced from eachother axially of the lower roller l and upper roller IE to form verticalchannels for the reception of the lower roll bearing l1 and receptionand guidance of the upper roll bearing carrier I8, said carrier, withits upper roll bearings being vertically extractible from the open upperend of the channel formed by the vertical flanges l2 and I3.

The bearing carriers l8 are carried by a yoke l9 provided with dependingends 20.

Pivotally associated with the yoke I9 is the upper cross bar 2| by meansof which torsion springs 22, mounted in the base l0 and provided withradially-extending arms 23 pivotally associated with upwardly-extendedconnector plates 24, may be associated with the upper roll so as tospring-urge said upper roll upon the lower roll.

The construction thus far described is described more in detail in theConarroe Patent 1,906,841 issued May 2nd, 1933.

In that construction cross bar 40 is provided with depending fingers 3|each of which is pivoted upon a pin 36 carried by the yoke 36, the axisof which is necessarily, when in working position, in the same verticalplane as the axes of the rolls 33 carried by the upwardly-extendingconnectors 28. I 5

In'order to obtain sufllcient stability of spring pressure in such aconstruction it was found necessary, as was pointed out in that patent,to slightly notch the finger to form a shallow pocket for the receptionof the roller 33, as other- 10 wise the cross head 40, in its medial andoperating position was too unstable. But it was also found that theprovision of such a stabilizing pocket made it necessary for theoperator, in case of accident, to exert a considerable degree of forcelaterally against the cross bar, to release the up-' per. roll from theoperating spring pressure.

I have overcome this difliculty, without the sacrifice of stability, inthe following manner:

In my present construction the cross head 2|, at 20.

each end, is provided with 9. depending finger having anoutwardly-projected and slightly upwardly inclined tip 26 adapted tounderride the roll 21 carried by the adjacent upwardly-extendingconnector 24, the same as in the above-men- 25 tioned Conarroeconstruction, but instead of providing a single-axis pivot pin for theconnection between yoke l9 and fingers 25, I provide a twoaxis pivot pin30 formed, as more clearly illustrated in Fig. 5, to afford two parallelfulcrums 30 3|, 3| arranged on opposite sides of the vertical plane ofthe axis of roller 21, these two axes 3|, 3| being most convenientlyformed by slightly rounding the upper edges of the pin 30 andpreferably, though not necessarily, forming a shallow clearance trough32 therebetween in order to insure against any such accumulation of lintor other waste between the pivot edges 3|, 3| as would interfere withproper operation of the device. The finger 25 forms a swinging carrierfor the tip 26, which tip has an overlapping cooperation with the roller21.

In order to cooperate with the two-axis pin 30, finger 25 is providedwith a polygonal perforation P having an upper surface 35 flanked ateach end by downwardly and outwardly inclined surfaces 36, 36 soproportioned, relative to pin 30, that the junctions between thesurfaces 35-36 will rest upon the edges 3|, 3|.

Perforation P as a whole is of suflicient width and height to affordfreedom of movement of finger 25 on finger 30 and, in order .to insuremaintenance of association of the fingers 25 and 30, the finger 30 atits outer end is provided with a laterally-extended tip 31.

With this arrangement a lateral force exerted upon cross head 2i, ineither direction will pivot the fingers 25 upon that axis 3| mostdistant from the applied force and the fingers i! will pivot thereon. Itwill be noted that the arc of swing of the upper surface of tip 20,about either one of .the pivot axes 3|, is almost tangent to the roll 21and, as the upper surface of the tip Il may now be perfectly smooth,very little lifting eflort upon the connectors 14, tending to furtherstress the springs 22. is necessary to withdraw tips 26 from beneathrolls 21. But it will be further noted that my construction providesample stability of working association the springs and the upper rollersIt became of the extended lateral support of finger 2| upon oppositesides of the vertical plane of the axis of roll 21.

It will be readily understood that while I have shown my improvedconnection in association with other details of wringer construction,the 'said improved connection may be used in various types or wringerswithout substantial modification.

The inner edges of the flanges l2, I! are spaced from each other sothat, unless deflected, water squeezed from the clothes near the ends ofthe rollers l5 and It, may, unless deflected, be projected down upon theexposed ends of the lower roller axle l5 and into the open bearings ofthe bearing blocks H.

In order to deflect this water I have provided the inexpensive sheetmetal guard or deflector shown in Figs. 2, 6 and '7, said deflectorcomprising a medial portion 40 having tips 40', 40, intermediateportions H, 4| and upper and lower portions 42, 42, each having tips42', 42' and each medially notched, at 43, to fit over the exposedportions of the upper and lower roller axles l6 and I5 immediatelyadjacent the ends of the rollers.

The upper and lower portions 42, 42 are ofiset from the plane of themiddle portion 40 an amount substantially equal to the thickness of theflanges l2, as shown in Fig. 6, so that, after the lower roller has beenplacedin position, 5 the deflectors may be telescoped over the flangesl2, between said flanges as clearly shown in Figs.

3 and 6.

I claim as my invention: I

1. In a wringer, the combination of a base 10 having verticallychanneled end standards eomprising laterally-spaced innerchannel-flanges, and a water-deflector having at each side projectionsspaced to telescope over one of said channel flanges, said deflectorbeing dimensioned to bridge the space between said channel-flanges andthe roller shafts. I

, 2. In a wringer, means for releasably connecting one of the tworollers to a spring, comprising two overlappable interlocking elements,a pivotally-supported swinging carrier for one of said elements, and twopivot axes for said carrier laterally spaced upon opposite sides of aplane including the axis of said one roller and the point ofinterlocking engagement of said overlapping elements, the engagementbetween axes and carrier permitting free rocking separation.

3. In a wringer means for releasably connecting one of the two rollersto a' spring, comprising a pivotally-supported swinging carrier and asupport therefor, one of said last-mentioned elements forming twolaterally-spaced parallel axes and the other having an axis-receivingperforation aflording two laterally-spaced contact lines for said axesand freely rookably separable therefrom, and two overlappable elementsone carried by the swinging carrier and the other connected to saidspring, the medial plane of engagement between said overlappableelements lying in a plane passing between said axes. 4o
